My invention relates to driving boxes, such'as are employed forjournalling the side` L frames oflocomotivesor cars to thejdriving orcarrying axles, more especially to outside journal yboxes adapted loruse on locomo/ tives where. the kspace Abetween the side yframesy isoccupied by the drivinggear mechanism..`

n It is among the objects oi this invention 'tof provide yfa `drivingbox comprising fa minimum number of partsthat shall be'readilyaccessible yfor the removal oi' the bearing member and vwhich shall bekof ysim-ple vand relativelyinexpensive construction. u n

f `Driving boxes heretofore employedl com. prise substantially box-shapemembers which are ,movably mounted between the pedestal jaws of theside-frame members having.. wearing `Shoes of a suitable bearingmaterial yinterposed therebetween." VThe boxes are? usually providedWithtlanged body porj tions which vengage the sides vof' the' shoemembel'stomaintain alinement and' to prevent binding with the axlemembers.V Such flanged boxfwas held in position by a pedestal binderwhich was adaptedto be removed and'thebox `was subsequently*removed by yf raisingthe side `frame abovethe wheel axle to permit the box to slidedown or by drop? ping the wheels and boxes. Y. My ypresent invention isdirected to dmv-@ ing-box structures which are adapted to bey f fmounted in,\or removed from, the side frame members ywithoutnecessitatingk the disman-f tling thereof, and such boxes are provided Vwithsuitable retaining blocks for mounting the' springv saddles andcrown brasses or v bearingblocks, all of which are held in theirrespective positions by a plurality of dowel ins.y ff The crown brass isremoved by raislng the `saddle above the retaining bloclrso thatthedowel pins are out 'of engagement withthelbe'aring block which is thenreadily removed by a suitable hook or the'like..

i f 'In the'ac'companying drawing,`constituting a part' hereof, and inwhich like reference charactersdesignate like parts, y f Figure 1 is afront elevational view taken along the line I-'I of Fig. 3, of a `drivebox embodying` the principles of this invention mounted between a pairof pedestal jaws of side-ramemember; I; f y 'j y f Fig. 2'is a verticalsectional view taken along the line II-II of Fig. 1; and

ylheqjou1nal.box structurel consistsf Aofa substantially ybox-shapeveasingy 1 .provided with extending iangepor't-ions 2 `r"whiehy are inr'sliding engagement Withtheshoesl'disv posed around the pedestal jaws.4Q lThe upperportion of the casing'fis provided with 'af projection 5having a recess 6 in vwhich Iaileg of a. spring saddle 7 is mounted.y'The saddle 7 supports a, spring- 8'` which isA fastened thereto byy aband 9L j Acrown brass or bear:

ing block kl()l is attached'to the portion `Qof thecasing by kmeans ofaplurality ofdowel-ly ypins llzwhich are lsecured to 'the spring sad#dles 7 and extendthrough the ycasir'ig into thebearing block 10. ,c "f

AV rectangular flange member y 12, having itsrv longest dimensioncorresponding `to l j the overall length ofthe box 1 from the endsotthe-flanges 2';andhaving` its shorter dimen sion slightly less than thedistance between 'the shoes y3 of the pedestalj aws, issecured; to thebox lon the rearportionthereof by a retaining ring 13 Awhichispressed'on the casfing 1. vThe rectangular member 12 constitutes the innera'nge'member of theboxj .which engages the pedestal shoeto main-1 tainalinement oftheboxv member with the" frame.y

- The drive boxv is adaptedtoverti'cal move-y mentbetween the pedestaljaws r and is fuirther journalled to a wheel axle 15 onewliicli it issupported 'by the crown brass orbe-,ar-` ingl block 10. The load of thevehicle is lsupported' through 'the drive springs 8, spring' saddle 7and the casing 1` lon thev axle 15B The drive box is retained betweenthe pedes-l tall jaws 4 by za pedestal" binder` 16 (Fig. 1). If it isdesired'to remove the bearing blockf 10, the vspring saddle 7 israised'to disengage 'the dowel pins 11 from the bearing v10 whichr maytheny be readily withdrawn ina 'suitable' manner, as by inserting akscrew bolt into the threaded opening 17. If it isdesired to re# move theentire box, it will not be necessary 'to raise the entire frame memberbut may be yaccomplished-by releasing the 'retaining ring 13 and movingthe rectangular flange member 12 angularly 909 so that its short'sidecorresponds :to thespace between the ped-y estaly shoes k3 Whichpermitsof removing the v box by pulling it straight 'forward from the yWheelaxle 15. f 1.

It Will be evident from the above descrip tion of my invention thatdriving boxes formed in accordance 'therewith constitute a simple'andinexpensive struct-ure all Lof thev parts of which are readilyaccessiblel for re'- moval to be repaired. or replaced. gThe struc'-ture herein employed does not require the l15l use of scre'vv'boltsorthe like and isre'adil Yassembled in its operating position on aWheellaxlebearing Without thel difficulty oiA fitting fthe membersbetween" the* pedestal ,n jaws which hasV 'heretoforebeen experienced.

Although I have described ya specific eme bodiment of my invention, itwill be l'obvious tothose skilled in the art that various-modi#iications may bemade in the details of construction Withoutdepartingfrom the principles herein set forth.
